Description

(V16199(V16199

Bei Kathodenröhren, die mit einer flachen Kathode ausgerüstet sind, ist die Stellung des ersten Gitters zur Kathodenfläche von wesentlicher Bedeutung.For cathode tubes that are equipped with a flat cathode, the position of the first grid to the cathode surface is essential.

Erfindungsgemäß werden Kathode und Gitter so zueinander angeordnet, daß ihre wirksamen Flächen sich in parallelen oder annähernd parallelen Ebenen befinden.According to the invention, the cathode and grid are arranged to one another that their effective surfaces are in parallel or approximately parallel planes.

Die Abbildung zeigt ein Ausführungsbeispiel. Auf dem Glasfuß./ sitzt beispielsweise der bekannte Glasrahmen r, in welchen die flache Kathode k federnd eingesetzt ist. Die Zuleitungsdrähte kz dienen für letztere als Stromzuführung, az und gz für Anode« und Gitter g. Die Kathode ist erfindungsgemäß so eingesetzt, daß ihre flachen Seiten parallel zu der wirksamen Fläche des ersten Gitters stehen, welches als Steuer- oder Raumladungsgitter sowie für jeden anderen Zweck verwendet werden kann. Durch diese Anordnung ist die Möglichkeit gegeben, geringste Abstände zwischen Kathode und Gitter herzustellen, so daß beste Ausnutzung der Kathodenoberfläche gewährleistet ist.The figure shows an exemplary embodiment. For example, the known glass frame r, in which the flat cathode k is resiliently inserted, sits on the glass base. The lead wires k z serve as a power supply for the latter, a z and g z for anode «and grid g. According to the invention, the cathode is used in such a way that its flat sides are parallel to the effective surface of the first grid, which can be used as a control or space charge grid and for any other purpose. This arrangement makes it possible to produce the smallest gaps between the cathode and grid, so that the best possible utilization of the cathode surface is guaranteed.
